Donald Trump has angered some and given others a chuckle with his response to a slain Muslim soldier's father, who railed against the Republican presidential candidate at the Democratic National Convention last week.

In interviews he gave following the speech by Khizr Khan, whose Army captain son was killed in Iraq in 2004, Trump assured voters that--despite what was said in the speech--he has made sacrifices for America.

"Who wrote that? Did Hillary's scriptwriters write it?" Trump said in an ABC interview. "I think I've made a lot of sacrifices. I work very, very hard."

When pressed by interviewer George Stephanopoulos, Trump named job creation as his sacrifice. "I've created thousands and thousands of jobs, tens of thousands of jobs, built great structures. I've had tremendous success. I think I've done a lot."
